Less than a day after lawyers for Britney Spears hammered out a visitation agreement with Kevin Federline and his attorney, Spears reunited with her two young sons on Saturday, E! Online reports.

She hadn't seen Sean Preston, 2, and Jayden James, 1, since she was carted off to a mental ward after a custodial standoff on Jan. 3. Her second stint at a hospital psychiatric ward led a judge to give her father, Jamie Spears, some control over the pop star's affairs, and Federline's attorney Mark Vincent Kaplan says Spears never would have gotten to see her kids had Jamie Spears not been involved.

"He gets a lot of credit for helping make this happen. But we've worked very hard with the conservator lawyers, as well, to make this all work." The two kids visited with their mother for three hours on Saturday morning. A source tells E! that Spears was not allowed to take the boys into another room without supervision.
